Wasting time shuffling over to your mailbox expectantly only to find out that it’s empty is now a thing of the past. Simply place the Postybell in your mailbox and let *it* keep track of incoming mail. Postybell includes a sensor that detects movement in the mailbox and a GSM module that sends an [alert to your smartphone](https://www.trendhunter.com/trends/informed-delivery1). The GSM technology means you don’t have to be within a particular distance from your mailbox, like with similar products that rely on WiFi or Bluetooth. In the digital age, we’re well-accustomed to getting alerts on our phones every time we get an email, so Postybell’s Israeli creators thought it was time to bring the same convenience to [snail mail](https://www.trendhunter.com/trends/stable). At present, the app is only configured for use with Android smartphones, but an iOS version is also on the horizon. ## Trend Insights (Trend Hunter) - Score: 1.9/10 - Popularity: 7% | Activity: 41% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### Why This Trend Is Growing - **Smart Mailboxes:** Opportunity for companies to innovate and create more advanced technology for mailboxes. - **GSM Notification Technology:** Opportunity to develop new products that use GSM technology for notifications, not just for mobile communication. - **Digital Mail Management:** Opportunity to create more ways to integrate physical mail into digital communication channels. ### Industries Being Reshaped - **Security:** Opportunity for security companies to develop more advanced technologies for tracking physical mail. - **Home Automation:** Opportunity for home automation companies to integrate mailboxes into their systems and offer more convenience. - **Logistics:** Opportunity for logistics companies to improve mail delivery services and offer more real-time tracking options. ## Related on Trend Hunter - [Connected Authentication Mailboxes](https://www.trendhunter.com/trends/custo-1.md) - [Drone-Compatible Smart Mailboxes](https://www.trendhunter.com/trends/smart-mailboxes.md) - [Durable Modern Mailboxes](https://www.trendhunter.com/trends/nonlocking-mailbox.md) - [Solar Parcel Postboxes](https://www.trendhunter.com/trends/royal-mail-solar-postboxes.md) - [Parcel-Friendly Mailbox Designs](https://www.trendhunter.com/trends/rmb2000-mailbox.md) - [Connected Porch Package Boxes](https://www.trendhunter.com/trends/smart-delivery-box.md) - [Connected Package Delivery Safes](https://www.trendhunter.com/trends/doorbox-smart-delivery-box.md) - [Delightful Smart Messaging Systems](https://www.trendhunter.com/trends/smart-messaging-system.md) - [Digital Sticky Reminders](https://www.trendhunter.com/trends/friendlystack-reminder.md)
